VS 2010 - Creating Delay In Between Two Commands Of Script
Jun 16, 2011
I am currently in the process of writing a demonstrative program that will generate a string of 9 random numbers in a textbox. Now my basic knowledge of VB 2010 allows me to do this but my goal is to delay the generation of this number sequence until the my progress bar has progressed to the end. How can I insert a delay after my button activates my progress bar/timer without stopping all function and usability of the program all together. The basic wait function seems to lock everything up for the allotted time and then the number instantly generates and the progress bar begins.
I have an application in which I save transactions. So I have a datagridview populated with records and i test for changes in the datatable when saving.then i loop through the changed rows and save in the following order:I have a command that saves a wage.then a command that saves interest.I use this to save as a transactiondate:
but sometimes the code is executing the two commands on the exact same time. Now I have a query that displays a running total and on order for the running total to work properly no two transactions should have the same datetime for a particular person.how can I add a delay between the two commands to ensure the datetimes are saved differently?
i have a web browser control, that refreshes pages on a loop after calling a few subs, i need to create a delay in the loop so that the page has a chance to refresh and redisplay before it loops again. i tried the code below, but it seemed to freeze the entire form, elements including, so the web browser didnt refresh before the loop, so how could i create a non form-freezing delay for a loop?
For count = 1 To 20 WebBrowser1.Navigate("URL") simcheckcheck()
I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.
I am writing a project for class and have come across a problem that I have been unable to solve and am loking for a little help. What I am trying to do is to implement a half second delay every time a flipper is flipped or reset. My example code of The flip and reset is below.
' Flipper 1 code If Flipper1.droppedLeft = False Then Flipper1.flip()
Due to use postmessage tow times, I want add a delay (50) between tow postmessage(), and my timer interval is 1000.
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick If CheckBox10.CheckState = CheckState.Checked Then st = Int(Val(TextBox17.Text) * 10)
[code]....
and I konw Thread.Sleep(50) is not good, but how to use timer stop here.
In my program I have a tab control with 4 tab pages. In the second tab page there is a lot of controls (about 50! includes buttons, labels, combo boxes, textboxes, option boxes). When user opens the program and want to navigate to tabpage 2 there is about 2-3 second delay showing tabpage. This problem only occur the first time, after that it just shows the page fine. I am not sure what is causing this lag but the program seems buggy and slow to user.
Is there a way to delay the start of a text file? I am using this to call the TXT file after clicking a button: (opens txt file)
Process.Start("text.txt")I was wondering if there was a command to delay the TXT file from opening for a number of seconds?I use this to delay the Splash Screen: (delayed 5 seconds)
Threading.Thread.Sleep(5000)Is there something similar for TXT files??
I am making a simulation of windows loading,Ive made it show the startup screen (startup.vb) and ive got the login screen (login.vb), how can I make it stay at the startup screen for a few seconds before using the startup.show() command.( if I can use that command?)
to some server via an UdpClient. However, I need to make sure that all commands send are separated by a 1 second delay. If there is no delay, two commands send within this 1 second timespan will not be received both; only the first or the second command will get through.he commands are sent in a background thread at the moment, because it might take some time before the command is sent. I keep looping until the command has been sent, like this:
vb.net Public Sub Send(command As String) Dim bytes = Me.GetCommandBytes(command)
I am currently creating a program to send keystokes to a program at certain intervals. I need the thread to delay between keystrokes, and i need to be able to have the user input the amount of delay from the GUI via textbox. I have it running perfect with Thread.Sleep(), but it just isn't consistent enough. How can I code it to be accurate to roughly 5ms up or down? thanks, and here is the code. This is in VB 2010 by the way.
After the 7th line I need a pause until a submit button pops up on the screen. The submit button is hidden until the getelementbyid.focus is run. I cant use webbrowser_documentcompleted because the submit only unhides itself, and I cant use Sleep() because that just stalls the whole block.
Anyone have any examples, or source code or SDK's that are FREE?I'd like to setup a simple voip program to play with.Was curious whats the simplest way of doing it, using UDP across an IP.I planned on having a server program, as i'd want multiple clients.My question is, how can i stream voice, without using alot of bandwidth with minimal delay between talking?
I'm having trouble opening and running DOS commands through VB Express.I'm trying to have VB open a command console and enter path to a batch file. So far I have not been able to get VB to open a console and enter any text.[URL} Here is the code I am using right now (without success)
Private Declare Function GetShortPathName Lib "kernel32" Alias "GetShortPathNameA" (ByVal longPath As String, ByVal shortPath As String, ByVal shortBufferSize As Int32) As Int32 Private Sub des_date_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles des_date.Click
Im just starting to develop an application using a SQL Database as the main datasource. Now im wondering is it better to use the in-built dataset adapters or write the querys yourself?
If its better to use the pre-generated scripts by using the Datasource UI, How can i use these datasets on a JOIN query?
Example Join SELECT column_name(s) FROM table_name1 JOIN table_name2 ON table_name1.column_name=table_name2.column_name
I prefer having total control for data access, populating recordsets (now datasets) precisely via a connection string and SQL select (or stored procedure call), etc.Now I wonder whether I really should be using the Data Sources option which just popped up on my radar? From the little I've seen so far, it seems to bind an entire table to a control, whereas most of the time I only need a small number of records from large tables.Before I spend a lot of time investigating, I hope a quick word from you might help me feel happier continuing as I am, or whether I need a kick up the backside towards a Better Way.
I need to build an forms app that 'posts' or 'sends' text commands to an external console process, called Minecraft Server It is a java-based process, filename 'minecraft_server.jar'. Run by my computer via 'java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui'. The Process ID I assume would change each time it's run. This process can be downloaded here: [URL]
I am guessing that I need to:
1) find the Process ID for it, based on its process details, such as Command Line
2) figure out a way to 'post' these commands, commands such as "stop" into the console window
I cannot have this process launched by my VB project.
I write in VB2010, the software should work with the external hardware via RS232, the thing is when I send a command to the external hardware I have to wait for a reply from the device that command was received, just after I got the answer I want to continue send another command, I have a long sequence of commands i'm supposed to send, but I need to know for sure that the commands were received before I go on to the next command. I did the following code, but I think the code is not effective, because sometimes I do not get an answer and then the whole sequence commands destroyed. Maybe you can help me optimize the code?

im trying to send RCon commands to a Call of duty: Black Ops game server.I read a thread from a few years back about sending RCon commands to a CoD 4 server, and all look promising until the application kept crashing when I pressed connect.

all I want is to be able to send a few commands to the server through an application.
I have an application, for sending SMS to mobile phones, using a GSM modem and AT commands. It works perfectly, except in one point. If the modem have some problem, for example doesn't have network, or even doesn't have a SIM card, I dont know if the message was sent or not. How can I test if the message was sucefully sent?
My project involves making a table database that displays student number, surname, first name, homeroom, and grade avg. Through SQL commands, there must be functions to add, update, delete, search by field, and save records to the database.I have already set the database up just fine and displayed it in a DataGridView. Through the DataGridView, I was able to go to the "Add Query" area, and I successfully made the queries necessary for searching by field. However, when I try to do anything other than a search using the query builder (ie start my SQL command with INSERT INTO or DELETE FROM), I ultimately get the message "Failed to get schema for this query"For example, this SQL code (to add an entry to the database) worked when I was in the Query Builder (and the entry that it made is still in the database), but when I finally tried to confirm it, I got the "Failed to get schema for this query" message.Being unable to add entries to the database this way, I tried to do it with textboxes on a form. Each textbox will have one of the fields, and at the click of a button, they would be put into the table. My code is below. I do not know what is wrong withit. When I run it, my fields do not appear on the DataGridView immediately, but I must run the program again to see it. The time after, the entry is gone. So I am not sure how exactly such entries are to be saved.

What is the best way to resize & move a form using just VB commands? I have a form that I need to set the Height and Top props, problem is that takes two calls and there is a noticable flicker. I tried using SuspendLayout/ResumeLayout, DoubleBuffered, swaping the top and height calls around, etc, but nothing seems to help. The test forms only have one small listview and one or two buttons.

I have a list of points X(horizontal), Y(vertical), and Z(depth). I want to be able to plot them out so they can be viewed and since it is 3d I want to be able to rotate the image as well. There would be a line connecting each point to the next, until the end of my list. If possible I would also like to be able to click on an individual point on the image and be able to tell where that point is in my list.The problem is I don't have any idea on where to start on this. I know how to create some pretty basic/genaric 2d bitmaps but 3d and some of the features are an entire different story.
i would like to get some ideas on how to connect computers to play a LAN game.. the deadline for this project will be on the 27th of march so.The game that i'll be making is a counter-strike-like 2d game.. is it possible that i can finish this project before its deadline?
I'm normally an ASP.NET developer but my latest project has me writing a console app. For this console app to function, it needs two executables, two DLLs, an XML file that should be configured with a WinForm I've developed (so another .exe), and a working folder should be created (for when my console app runs). Further, it would be nice to have it automatically set up a Scheduled Task for batch operation.How do I package the various files into a self-extracting package? I'm playing with WinZip's self-extractor creator and it's okay, but I don't see a way for it to launch further processes, such as creating a working folder for the console or launching the WinForm above.Is there a way to create an auto-extractor in VB.NET where zipped contents are part of the "payload" of the .exe? It seems to me this would give me the most flexibility, as I could write a WinForm that does everything.
I'm a VB.net newbie and trying to write a simple program for installing in a few of my company's computers, most of which still use Windows XP.How can I specify when publishing in VS2010 that the program is for installation in XP?
